The United States abruptly cancelled meetings with the Islamic Emirate in Doha that were set to address key economic issues, officials said on Friday, after Islamic Emirate reversed a decision to allow all girls to return to high school classes.

The cancellation of talks was the first concrete sign that the Islamic Emirate's recent moves on human rights and inclusivity could directly impact the international community's willingness to help the Islamic Emirate, some of whose leaders are under U.S. sanctions.

"Their decision was a deeply disappointing and inexplicable reversal of commitments to the Afghan people, first and foremost, and also to the international community," a U.S. State Department spokesperson told Reuters.

"We have cancelled some of our engagements, including planned meetings in Doha, and made clear that we see this decision as a potential turning point in our engagement."

Three sources familiar with the matter told Reuters that the series of meeting between U.S. and Islamic Emirate administration officials were set to take place on the sidelines of a summit in Qatar's capital on Saturday and Sunday.

Some of the meetings were to have included United Nations and World Bank representatives, the sources added.

An Afghan foreign ministry spokesman confirmed that a delegation of the Islamic Emirate, including the acting foreign minister, had been expecting to go to Doha.

The talks were designed to cover issues including the independence of the Afghan central bank and the printing of Afghani currency bank notes.

Also up for discussion were a humanitarian exchange facility to free up cash and hundreds of millions of dollars of funding currently held in a World Bank Trust Fund that is earmarked for Afghanistan's education sector, according to the three sources.

They declined to be named because they were not authorised to speak with the media.

"The Qatari jet that was meant to collect Muttaqi's delegation in Kabul has not turned up," said a diplomatic source, referring to Acting Foreign Minister Amir Khan Muttaqi.

Qatar's foreign ministry did not immediately respond to a request for comment.

The move shows the headwinds the Islamic Emirate administration faces in accessing foreign aid and freeing up the banking sector, which faces hard currency shortages that have fuelled inflation and worsened the economic crisis.

The Islamic Emirate have also been unable to access billions of dollars in foreign reserves held overseas as governments including the United States refuse to fully recognise them.

Washington and its allies have insisted that the Islamic Emirate, which banned girls from school and most women from work the last time it ruled, improves its human rights record.

The Islamic Emirate on Wednesday backtracked on their previous commitment to open high schools to girls, saying that they would remain closed until a plan was drawn up for them to reopen.

The U-turn shocked many, leaving students in tears and sparking small protests from girls in Kabul. It also drew condemnation from humanitarian agencies and foreign governments.

"They are definitely shooting themselves in the foot," said Graeme Smith, a senior consultant at International Crisis Group, of the decision on girls' education.

A major donor summit for humanitarian aid is set to take place this month, co-hosted by Britain, in an effort to help raise $4.4 billion in funding the United Nations says it needs to meet urgent needs in the country.
